They are on a cold trail And running out of time. Rhea Reilly is certain her twin sister's sudden disappearance six months ago wasn't a suicide, no matter what Colorado authorities think. She can't afford to trust police detective Jackson Whitaker--even if he's risking his career to uncover the truth. But a lethal trail of lies is drawing them together...and into an inescapable trap. From Harlequin Intrigue: Seek thrills. Solve crimes. Justice served.
